B. Description of Related Art

Ageing, chronic exposure to adverse environmental factors, malnutrition, fatigue, etc., can change the visual appearance, physical properties, or physiological functions of skin in ways that are considered visually undesirable. The most notable and obvious changes include the development of fine lines and wrinkles, loss of elasticity, increased sagging, loss of firmness, loss of color evenness or tone, coarse surface texture, and mottled pigmentation. Less obvious, but measurable changes which occur as skin ages or endures chronic environmental insult include a general reduction in cellular and tissue vitality, reduction in cell replication rates, reduced cutaneous blood flow, reduced moisture content, accumulated errors in structure and function, alterations in the normal regulation of common biochemical pathways, and a reduction in the skin's ability to remodel and repair itself. Many of the alterations in appearance and function of the skin are caused by changes in the outer epidermal layer of the skin, while others are caused by changes in the lower dermis.

Previous attempts to improve the visual appearance of skin with known skin active-ingredients have been shown to have various drawbacks such as skin irritation and prolonged recovery periods.

Example 1 Materials and Methods for Obtaining Extracts

The extracts identified in Table 1 were prepared from the whole plant. Each plant was individually obtained, ground, and dried, to produce a powder. The powder was treated according to the process described in FIG. 1. Each extract in Table 1 was prepared by and provided to the inventors by Kunming Institute of Botany, Chinese Academy of Sciences, Yunnan, CHINA.

Example 2 Efficacy of Extracts

Each extract prepared according to the process described in Example 1 was subjected to a variety of assays to determine their skin efficacy (note the H₂0 part (v) extract was used for testing—see FIG. 1). The following Table 1 provides a summary of these data. A description of the assays used to obtain these data is provided below Table 1.

Alternatively, the extracts can be used individually, which still can result in a product having multiple benefits.

Tumor Necrosis Factor Alpha (TNF-α) Assay: The prototype ligand of the TNF superfamily, TNF-α, is a pleiotropic cytokine that plays a central role in inflammation. Increase in its expression is associated with an up regulation in pro-inflammatory activity. This bioassay analyzes the effect of extracts on the production of TNF-α by human epidermal keratinocytes. The endpoint of this assay is a spectrophotometric measurement that reflects the presence of TNF-α and cellular viability. The assay employs the quantitative sandwich enzyme immunoassay technique whereby a monoclonal antibody specific for TNF-α has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TNF-α present is bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked polyclonal antibody specific for TNF-α is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TNF-α bound in the initial step using a microplate reader for detection at 450 nm. The color development is stopped and the intensity of the color is measured.

Subconfluent normal human adult keratinocytes (Cascade Biologics) cultivated in EpiLife standard growth medium (Cascade Biologics) at 37° C. in 5% CO₂, were treated with phorbol 12-myristate 13-acetate (PMA, 10 ng/ml, Sigma Chemical, #P1585-1MG) and each of the extracts identified in Table 1 for 6 hours. PMA has been shown to cause a dramatic increase in TNF-α secretion which peaks at 6 hours after treatment. Following incubation, cell culture medium was collected and the amount of TNF-α secretion quantified using a sandwhich enzyme linked immuno-sorbant assay (ELISA) from R&D Systems (#DTA00C).

Antioxidant (AO) Assay: An in vitro bioassay that measures the total anti-oxidant capacity of an extract. The assay relies on the ability of antioxidants in the sample to inhibit the oxidation of ABTS® (2,2′-azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS®•+ by metmyoglobin. The antioxidant system of living organisms includes enzymes such as superoxide dismutase, catalase, and glutathione peroxidase; macromolecules such as albumin, ceruloplasmin, and ferritin; and an array of small molecules, including ascorbic acid, α-tocopherol, β-carotene, reduced glutathione, uric acid, and bilirubin. The sum of endogenous and food-derived antioxidants represents the total antioxidant activity of the extracellular fluid. Cooperation of all the different antioxidants provides greater protection against attack by reactive oxygen or nitrogen radicals, than any single compound alone. Thus, the overall antioxidant capacity may give more relevant biological information compared to that obtained by the measurement of individual components, as it considers the cumulative effect of all antioxidants present in plasma and body fluids. The capacity of the antioxidants in the sample to prevent ABTS oxidation is compared with that of Trolox, a water-soluble tocopherol analogue, and is quantified as molar Trolox equivalents.

Anti-Oxidant capacity kit #709001 from Cayman Chemical (Ann Arbor, Mich. USA) was used as an in vitro bioassay to measure the total anti-oxidant capacity of each of the extracts identified in Table 1. The protocol was followed according to manufacturer recommendations. The assay relied on antioxidants in the sample to inhibit the oxidation of ABTS® (2,2′-azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS®•+ by metmyoglobin. The capacity of the antioxidants in the sample to prevent ABTS oxidation was compared with that Trolox, a water-soluble tocopherol analogue, and was quantified as a molar Trolox equivalent.

Tyrosinase Activity Assay: In mammalian cells, tyrosinase catalyzes two steps in the multi-step biosynthesis of melanin pigments from tyrosine (and from the polymerization of dopachrome). Tyrosinase is localized in melanocytes and produces melanin (aromatic quinone compounds) that imparts color to skin, hair, and eyes.

Purified mushroom tyrosinase (Sigma) was incubated with its substrate L-Dopa (Fisher) in the presence or absence of each of the extracts in Table 1. Pigment formation was evaluated by colorimetric plate reading at 490 nm. The percent inhibition of mushroom tyrosinase activity was calculated compared to non-treated controls to determine the ability of test extracts to inhibit the activity of purified enzyme. Test extract inhibition was compared with that of kojic acid (Sigma).

Matrix Metalloproteinase Enzyme Activity (MMP1) Assay: An in vitro matrix metalloprotease (MMP) inhibition assay. MMPs are extracellular proteases that play a role in many normal and disease states by virtue of their broad substrate specificity. MMP1 substrates include collagen IV. The Molecular Probes Enz/Chek Gelatinase/Collagenase Assay kit (#E12055) utilizes a fluorogenic gelatin substrate to detect MMP1 protease activity. Upon proteolytic cleavage, bright green fluorescence is revealed and may be monitored using a fluorescent microplate reader to measure enzymatic activity.

The Enz/Chek Gelatinase/Collagenase Assay kit (#E12055) from Invitrogen was used as an in vitro assay to measure MMP1 enzymatic activity for each of the extracts identified in Tables 1-3. The assay relies upon the ability of purified MMP 1 enzyme to degrade a fluorogenic gelatin substrate. Once the substrate is specifically cleaved by MMP1 bright green fluorescence is revealed and may be monitored using a fluorescent microplate reader. Test materials are incubated in the presence or absence of the purified enzyme and substrate to determine their protease inhibitor capacity.

Lipoxygenase (LO) Assay: An in vitro lipoxygenase (LO) inhibition assay. LOs are non-heme iron-containing dioxygenases that catalyze the addition of molecular oxygen to fatty acids. Linoleate and arachidonate are the main substrates for LOs in plants and animals. Arachadonic acid may then be converted to hydroxyeicosotrienenoic (HETE) acid derivatives, that are subsequently converted to leukotirenes, potent inflammatory mediators. This assay provides an accurate and convenient method for screening lipoxygenase inhibitors by measuring the hydroperoxides generated from the incubation of a lipoxygenase (5-, 12-, or 15-LO) with arachidonic acid.

The Colorimetric LO Inhibitor screening kit (#760700, Cayman Chemical) was used to determine the ability of each of the extracts identified in Tables 1-3 to inhibit enzyme activity. Purified 15-lipoxygenase and test extracts were mixed in assay buffer and incubated with shaking for 10 min at room temperature. Following incubation, arachidonic acid was added to initiate the reaction and mixtures incubated for an additional 10 min at room temperature. Colorimetric substrate was added to terminate catalysis and color progression was evaluated by fluorescence plate reading at 490 nm. The percent inhibition of lipoxyganse activity was calculated compared to non-treated controls to determine the ability of test extracts to inhibit the activity of purified enzyme.

Example 3 Particular Combinations of Extracts

Based, in part, on the above data, it was discovered that a combination of an aqueous extract from the whole plant of Boehmeria platyphylla, an aqueous extract from the whole plant of Cratoxylum prunifolium, and an aqueous extract from the whole plant of Excoecaria acerifolia can be used to inhibit/reduce the activity of MMP-1 in skin cells. This can lead to increased collagen within skin, which can reduce the appearance of fine lines and wrinkles. Aqueous extracts of the whole plant were used to obtain this data (see FIG. 1, H₂O part (v)). This combination can also be used to inhibit/reduce lipoxygenase activity, TNF-α activity, and protect skin cells from oxidative damage caused by free-radicals and reactive oxygen species. The use of whole plant leads to an extract having different ingredients when compared, with an extract from a portion of the same plant (e.g., leaf or flower extract).

A further discovery was the combination of an aqueous extract from the whole plant of Boehmeria platyphylla, an aqueous extract from the whole plant of Karelinia caspica, and an aqueous extract from the whole plant of Inula helianthus-aquatica to inhibit/reduce TNF-α activity in said skin. This is beneficial in that it can prevent the inflammation cascade, which can lead to damaged skin cells and present as inflamed or erythemic skin. The combination can also inhibit MMP-1 activity and lipoxygenase activity in said skin and protect skin cells from oxidative damage caused by free-radicals and reactive oxygen species. As previously noted, aqueous extracts of the whole plant were used to obtain this data (see FIG. 1, H₂O part (v)). The use of whole plant leads to an extract having different ingredients when compared, with an extract from a portion of the same plant (e.g., leaf or flower extract).

An additional discovery was the combination of an aqueous extract from the whole plant of Artabotrys hexapetalus, an aqueous extract from the whole plant of Sassafras tzumu, and an aqueous extract from the whole plant of Prunus salicina to protect skin cells from oxidative damage caused by free-radicals and reactive oxygen species. This combination can also inhibit MMP-1 and lipoxygenase activity in skin cells. As previously noted, aqueous extracts of the whole plant were used to obtain this data (see FIG. 1, H₂O part (v)). Again, the use of whole plant leads to an extract having different ingredients when compared, with an extract from a portion of the same plant (e.g., leaf or flower extract).

Another discovery is the use of an aqueous extract from the whole plant of Rhododendron moulmainense to inhibit/reduce tyrosinase activity in skin cells. By attacking the tyrosinase pathway, a reduction in melanin production can be obtained. This allows for the skin to appear lighter, thus reducing the appearance of dark spots, liver spots, age spots, sun spots, hyperpigmented skin, and melasmic skin. The addition of aqueous extracts from the whole plants of Calliandra haematocephala and Xylosma japonicum can further help the skin by inhibiting/reducing MMP-1 and lipoxygenase activity in the skin cells. As previously noted, aqueous extracts of the whole plant were used to obtain this data (see FIG. 1, H₂O part (v)). Again, the use of whole plant leads to an extract having different ingredients when compared, with an extract from a portion of the same plant (e.g., leaf or flower extract).

Example 5 Assays that can be Used to Test Compositions

The efficacy of compositions comprising the plant extracts identified throughout the specification, or a combination of such extracts (including, for example, the formulations identified in Tables 2-9), can be determined by methods known to those of ordinary skill in the art. The following are non-limiting assays that can be used in the context of the present invention. It should be recognized that other testing procedures can be used, including, for example, objective and subjective procedures.

Erythema Assay: An assay to measure the reduction of skin redness can be evaluated using a Minolta Chromometer. Skin erythema may be induced by applying a 0.2% solution of sodium dodecyl sulfate on the forearm of a subject. The area is protected by an occlusive patch for 24 hrs. After 24 hrs, the patch is removed and the irritation-induced redness can be assessed using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. Immediately after reading, the area is treated with a formula containing any one, or any combination thereof, of the extracts identified throughout the specification. In particular aspects, the extract can be a Camptotheca acuminate extract, a Loropetalum chinensis extract, a Chrysalidocarpus lutscens extract, or a Potamogenton perforliatus extract, or any combination thereof. Repeat measurements are taken at regular intervals to determine the formula's ability to reduce redness, inflammation, or skin irritation.

Skin Moisture/Hydration Assay: Skin moisture/hydration benefits can be measured by using impedance measurements with the Nova Dermal Phase Meter. The impedance meter measures changes in skin moisture content. The outer layer of the skin has distinct electrical properties. When skin is dry it conducts electricity very poorly. As it becomes more hydrated increasing conductivity results. Consequently, changes in skin impedance (related to conductivity) can be used to assess changes in skin hydration. The unit can be calibrated according to instrument instructions for each testing day. A notation of temperature and relative humidity can also be made. Subjects can be evaluated as follows: prior to measurement they can equilibrate in a room with defined humidity (e.g., 30-50%) and temperature (e.g., 68-72° C.). Three separate impedance readings can be taken on each side of the face, recorded, and averaged. The T5 setting can be used on the impedance meter which averages the impedance values of every five seconds application to the face. Changes can be reported with statistical variance and significance.

Skin Clarity and Reduction in Freckles and Age Spots Assay: Skin clarity and the reduction in freckles and age spots can be evaluated using a Minolta Chromometer. Changes in skin color can be assessed to determine irritation potential due to product treatment using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. This is used to determine whether a composition is inducing irritation. The measurements can be made on each side of the face and averaged, as left and right facial values. Skin clarity can also be measured using the Minolta Meter. The measurement is a combination of the a*, b, and L values of the Minolta Meter and is related to skin brightness, and correlates well with skin smoothness and hydration. Skin reading is taken as above. In one non-limiting aspect, skin clarity can be described as L/C where C is chroma and is defined as (a²+b²)^(1/2).

Skin Dryness, Surface Fine Lines, Skin Smoothness, and Skin Tone Assay: Skin dryness, surface fine lines, skin smoothness, and skin tone can be evaluated with clinical grading techniques. For example, clinical grading of skin dryness can be determined by a five point standard Kligman Scale: (0) skin is soft and moist; (1) skin appears normal with no visible dryness; (2) skin feels slightly dry to the touch with no visible flaking; (3) skin feels dry, tough, and has a whitish appearance with some scaling; and (4) skin feels very dry, rough, and has a whitish appearance with scaling. Evaluations can be made independently by two clinicians and averaged.

Clinical Grading of Skin Tone Assay: Clinical grading of skin tone can be performed via a ten point analog numerical scale: (10) even skin of uniform, pinkish brown color. No dark, erythremic, or scaly patches upon examination with a hand held magnifying lens. Microtexture of the skin very uniform upon touch; (7) even skin tone observed without magnification. No scaly areas, but slight discolorations either due to pigmentation or erythema. No discolorations more than 1 cm in diameter; (4) both skin discoloration and uneven texture easily noticeable. Slight scaliness. Skin rough to the touch in some areas; and (1) uneven skin coloration and texture. Numerous areas of scaliness and discoloration, either hypopigmented, erythremic or dark spots. Large areas of uneven color more than 1 cm in diameter. Evaluations were made independently by two clinicians and averaged.

Clinical Grading of Skin Smoothness Assay: Clinical grading of skin smoothness can be analyzed via a ten point analog numerical scale: (10) smooth, skin is moist and glistening, no resistance upon dragging finger across surface; (7) somewhat smooth, slight resistance; (4) rough, visibly altered, friction upon rubbing; and (1) rough, flaky, uneven surface. Evaluations were made independently by two clinicians and averaged.

Skin Smoothness and Wrinkle Reduction Assay with Methods Disclosed in Packman et al. (1978): Skin smoothness and wrinkle reduction can also be assessed visually by using the methods disclosed in Packman et al. (1978). For example, at each subject visit, the depth, shallowness and the total number of superficial facial lines (SFLs) of each subject can be carefully scored and recorded. A numerical score was obtained by multiplying a number factor times a depth/width/length factor. Scores are obtained for the eye area and mouth area (left and right sides) and added together as the total wrinkle score.

Skin Firmness Assay with a Hargens Ballistometer: Skin firmness can be measured using a Hargens ballistometer, a device that evaluates the elasticity and firmness of the skin by dropping a small body onto the skin and recording its first two rebound peaks. The ballistometry is a small lightweight probe with a relatively blunt tip (4 square mm-contact area) was used. The probe penetrates slightly into the skin and results in measurements that are dependent upon the properties of the outer layers of the skin, including the stratum corneum and outer epidermis and some of the dermal layers.

Skin Softness/Suppleness Assay with a Gas Bearing Electrodynamometer: Skin softness/suppleness can be evaluated using the Gas Bearing Electrodynamometer, an instrument that measures the stress/strain properties of the skin. The viscoelastic properties of skin correlate with skin moisturization. Measurements can be obtained on the predetermined site on the cheek area by attaching the probe to the skin surface with double-stick tape. A force of approximately 3.5 gm can be applied parallel to the skin surface and the skin displacement is accurately measured. Skin suppleness can then be calculated and is expressed as DSR (Dynamic Spring Rate in gm/mm).

Appearance of Lines and Wrinkles Assay with Replicas: The appearance of lines and wrinkles on the skin can be evaluated using replicas, which is the impression of the skin's surface. Silicone rubber like material can be used. The replica can be analyzed by image analysis. Changes in the visibility of lines and wrinkles can be objectively quantified via the taking of silicon replicas form the subjects' face and analyzing the replicas image using a computer image analysis system. Replicas can be taken from the eye area and the neck area, and photographed with a digital camera using a low angle incidence lighting. The digital images can be analyzed with an image processing program and the are of the replicas covered by wrinkles or fine lines was determined.

Surface Contour of the Skin Assay with a Profilometer/Stylus Method: The surface contour of the skin can be measured by using the profilometer/Stylus method. This includes either shining a light or dragging a stylus across the replica surface. The vertical displacement of the stylus can be fed into a computer via a distance transducer, and after scanning a fixed length of replica a cross-sectional analysis of skin profile can be generated as a two-dimensional curve. This scan can be repeated any number of times along a fix axis to generate a simulated 3-D picture of the skin. Ten random sections of the replicas using the stylus technique can be obtained and combined to generate average values. The values of interest include Ra which is the arithmetic mean of all roughness (height) values computed by integrating the profile height relative to the mean profile height. Rt which is the maximum vertical distance between the highest peak and lowest trough, and Rz which is the mean peak amplitude minus the mean peak height. Values are given as a calibrated value in mm. Equipment should be standardized prior to each use by scanning metal standards of know values. Ra Value can be computed by the following equation: R_(a)=Standardize roughness; l_(m)=the traverse (scan) length; and y=the absolute value of the location of the profile relative to the mean profile height x-axis).

MELANODERM™ Assay: In other non-limiting aspects, the efficacy of the compositions of the present invention can be evaluated by using a skin analog, such as, for example, MELANODERM™. Melanocytes, one of the cells in the skin analog, stain positively when exposed to L-dihydroxyphenyl alanine (L-DOPA), a precursor of melanin. The skin analog, MELANODERM™, can be treated with a variety of bases containing the compositions and whitening agents of the present invention or with the base alone as a control. Alternatively, an untreated sample of the skin analog can be used as a control.

ORAC Assay: Oxygen Radical Absorption (or Absorbance) Capacity (ORAC) of the aromatic skin-active ingredients and compositions can also be assayed by measuring the antioxidant activity of such ingredients or compositions. This assay can quantify the degree and length of time it takes to inhibit the action of an oxidizing agent such as oxygen radicals that are known to cause damage cells (e.g., skin cells). The ORAC value of the aromatic skin-active ingredients and compositions can be determined by methods known to those of ordinary skill in the art (see U.S. Publication Nos. 2004/0109905 and 2005/0163880; Cao et al. (1993)), all of which are incorporated by reference). In summary, the assay described in Cao et al. (1993) measures the ability of antioxidant compounds in test materials to inhibit the decline of B-phycoerythrm (B-PE) fluorescence that is induced by a peroxyl radical generator, AAPH.

Matrix Metalloproteinase Enzyme Activity (MMP3; MMP9) Assay: An in vitro matrix metalloprotease (MMP) inhibition assay. MMPs are extracellular proteases that play a role in many normal and disease states by virtue of their broad substrate specificity. MMP3 substrates include collagens, fibronectins, and laminin; while MMP9 substrates include collagen VII, fibronectins and laminin. Using Colorimetric Drug Discovery kits from BioMol International for MMP3 (AK-400) and MMP-9 (AK-410), this assay is designed to measure protease activity of MMPs using a thiopeptide as a chromogenic substrate (Ac-PLG-[2-mercapto-4-methyl-pentanoyl]-LG-OC2H5)5,6. The MMP cleavage site peptide bond is replaced by a thioester bond in the thiopeptide. Hydrolysis of this bond by an MMP produces a sulfhydryl group, which reacts with DTNB [5,5′-dithiobis(2-nitrobenzoic acid), Ellman's reagent] to form 2-nitro-5-thiobenzoic acid, which can be detected by its absorbance at 412 nm (ε=13,600 M-1 cm⁻¹ at pH 6.0 and above 7).

B16 Melanogenesis Assay: Melanogenesis is the process by which melanocytes produce melanin, a naturally produced pigment that imparts color to skin, hair, and eyes. Inhibiting melanogenesis is beneficial to prevent skin darkening and lighten dark spots associated with aging. This bioassay utilizes B16-F1 melanocytes (ATCC), an immortalized mouse melanoma cell line, to analyze the effect of compounds on melanogenesis. The endpoint of this assay is a spectrophotometric measurement of melanin production and cellular viability. B16-F1 melanocytes, can be cultivated in standard DMEM growth medium with 10% fetal bovine serum (Mediatech) at 37° C. in 10% CO₂, and treated with each of the extracts identified in the specification. Following incubation, melanin secretion can be measured by absorbance at 405 nm and cellular viability can be quantified.

Collagen Stimulation Assay: Collagen is an extracellular matrix protein critical for skin structure. Increased synthesis of collagen helps improve skin firmness and elasticity. This bioassay analyzes the effect of extracts on the production of procollagen peptide (a precursor to collagen) by human epidermal fibroblasts. The endpoint of this assay is a spectrophotometric measurement that reflects the presence of procollagen peptide and cellular viability. The assay employs the quantitative sandwich enzyme immunoassay technique whereby a monoclonal antibody specific for procollagen peptide has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any procollagen peptide present is bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked polyclonal antibody specific for procollagen peptide is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of procollagen peptide bound in the initial step using a microplate reader for detection at 450 nm. The color development is stopped and the intensity of the color is measured.

In particular, the assay could be performed as follows: subconfluent normal human adult epidermal fibroblasts (Cascade Biologics) cultivated in standard DMEM growth medium with 10% fetal bovine serum (Mediatech) at 37° C. in 10% CO₂, can be treated with each of the extracts identified in the specification. Following incubation, cell culture medium can be collected and the amount of procollagen peptide secretion can be quantified using a sandwhich enzyme linked immuno-sorbant assay (ELISA) from Takara (#MK101).
